Andrzej, do you use the Kodak GEM PRO for digital noise or film grain?

If the original post is about film grain, Noise Ninja is not the right software for that - Neat Image handles it well, but if there is also good experience for this with Kodak GEM PRO I'm interested to hear more about it.

Try Kodak GEM Pro plug-in! I think this is the best, all-around, very easy to use and effective noise-reduction software around. Stopped using NeatImage ever since!I also found Kodak SHO Pro plug-in very effective for shadow recovery, much "better" than Shadow Illuminator in my oppinion.

I use GEM Pro for "cleaning" digital images (taken with Leica Digilux 2). All "plug-ins" are "effects", i.e. they DO "change" (distort) the image in some way or another. I think that GEM Pro, with a little bit of tweeking, delivers a "clean", nice-looking image, basically free of any noise and with all "details" intact. I found NeatImage-processed images much more "plasticky" after processing...maybe all of this is only true for Leica?

I agree with Jonathan. I've been using Neat Image extensively for removing grain from film scans and there is nothing plastic-y in the results. It comes out very natural-looking while retaining very good detail provided you take the time to profile properly and tweak further as necessary. It is a bit of a balancing act, but not a very demanding one.
